Hello, I bought an Intel Core i3 530 Processor and a ECS P55H-CM (V1.0) Motherboard - Intel P55, Socket LGA1156. I plugged everything in correctly but when I turn the system on, the power supply cycles between on and off, never staying on. Someone said it might be a voltage issue and I have to set jumpers on the motherboard. Does anyone know if this is correct and/or what the proper setting is (Ultra LSP550 550-Watt Power Supply, in the USA)

No. Power supplies are largely "plug 'n play". There are no jumpers on the motherboard that have any effect on the PSU.
I'd try a better quality PSU (Corsair and Antec are my choices) if I were you.
I checked it over and found the problem. The motherboard had two power connections, a 24 pin and a 4 pin. I had only connected the 24 pin. After I also connected the 4 pin, it worked.
The 4 pin connector provides power to the CPU. I can see your system not booting. But the constant restart is more than a little unusual.
